From: Leo Yan <leo.yan@linaro.org> mainline inclusion from mainline-v5.11-rc1 commit c185f1cde466 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4NGPV CVE: NA ------------------------------------------------- Include header linux/bitops.h, directly use its BIT() macro and remove the self defined macros. Committer notes: Use BIT_ULL() instead of BIT to build on 32-bit arches as mentioned in review by Andre Przywara <andre.przywara@arm.com>. I noticed the build failure when crossbuilding to arm32 from x86_64.
